Black smoke?

<< < (9/9)

Time out, If youre gonna start talking physics, Im on my way........ :?

You are absolutely right, and it was a bit of an abstract example... what I was getting at is that there is a relationship between the temperature of the gas and it's volume.. and hence its rate of flow through a given aperture.

Bear with me... it's been a few years since I did thermodynamics and I'm a bit rusty !    <potters off to brush up on adiabatic and isothermal theory>

Diabetic what.......
Its insulin you need..........
 :shock:

Lets just put turbocharger operation down to the black magic that makes the rest of the engine work, (bit like the smoke that is contained within wires)

As far as the widget goes that stops black smoke(isnt that where we began)  If it affects the EGR valve, all its doin is allowing the engine to breath 100% fresh air(not tainted with Re-burnt exh gasses) This will make the engine run cleaner and with more power, but allow the exhaust gas to build up NOX(oxides of nitrogen). Why bother, just put a blank over the egr and have done!!!!!!!!!!!!!!!!!!!!!!!

Does this relate directly to a 300TDi, or is it for info/guidance only?

Is it worth doing these adjustments without upgrading the intercooler?

Budgie:
Gords,
Although the site is for the Dodge Ram, the 200 & 300 TDi's use the same injection pump as the Ram so the alterations relate directly to them and they will work with the standard intercooler, although the amount of alteration required will be less. :D

Do a little adjustment at a time and test the results is the best way to go, and make a note of what you've done so you can put it back to standard if it doesn't work!! I would work on one thing at a time, start with the diaphram, then the smoke screw, then the star wheel. I've only played with these 3 as that was enough for me, it started smoking too much when I had a go with the screw on the back of the pump so I put it back to normal.

The one that's easiest to do is the diaphram, if you have the standard intercooler then turn the diaphram no more than 90 degrees and see what a difference it makes. If it smokes too much then turn it back a little.  :wink:
